[0048] This utility model discloses a remote control device 100 for a mobile X-ray machine 200. The remote control device 100 includes a wireless remote control component 10 and a wireless receiving component 20. The wireless remote control component 10 includes a first controller 101, a transmitting module 102, and a first antenna 103. The first controller 101 is used to generate a control signal, the transmitting module 102 is configured to convert the control signal into a radio frequency (RF) signal, and the first antenna 103 is used to transmit the RF signal. The wireless receiving component 20 includes a second controller 201, a receiving module 202, and a second antenna 203. The second antenna 203 is used to receive the RF signal, and the receiving module 202 is used to receive the RF signal and decode it into a control signal. The second controller 201 is electrically connected to the device interface of the mobile X-ray machine 200 and controls the mobile X-ray machine 200 to perform exposure according to the control signal. The control signal is a UHF radio frequency (RF) signal.

[0049] In this embodiment, wireless control based on UHF radio frequency signals has a long transmission distance, strong diffraction capability, and weaker attenuation than Bluetooth and infrared. Wireless remote controls using UHF video signals can well meet the needs of compartmentalized operation. The frequency band of the UHF radio frequency signal is 400MHz to 470MHz. The transmitting module 102 is used to convert the control signal into a radio frequency signal and transmit it, while the receiving module 202 is used to receive the radio frequency signal and decode it into a control signal. The first controller 101 and the second controller 201 are microcontrollers or logic circuits used to generate control signals or process received signals.

[0050] The wireless remote control component 10 also includes a button 104, which is electrically connected to the first controller 101. The button 104 is configured such that when it is pressed, the first controller 101 generates the control signal. When a user presses the button 104 on the wireless remote control component 10, the first controller 101 generates a specific coded signal (control signal). This control signal is typically a digital sequence used to represent different control commands, such as "on" or "off".

[0051] The wireless receiving component 20 also includes a relay 204, which is electrically connected to the mobile X-ray machine 200. The second controller 201 is electrically connected to the relay 204 and controls the opening and closing of the relay 204 to control the on / off state of the mobile X-ray machine 200. Using a relay 204 to control the on / off state of the mobile X-ray machine 200 ensures that the control process is isolated from the equipment circuitry of the mobile X-ray machine 200, making it safe and reliable.

[0052] The wireless remote control component 10 further includes a button 104 electrically connected to the first controller 101. The button 104 is configured such that when the button 104 is pressed, the first controller 101 generates the control signal. The button includes a first button and a second button, and the relay 204 includes a first relay and a second relay. When the first button is pressed, the first controller 101 generates a first control signal to control the opening and closing of the first relay. When the second button is pressed, the first controller 101 generates a second control signal to control the opening and closing of the second relay.

[0053] For example, pressing the first button activates the first relay, closes the two-way switch of the first relay, and the mobile X-ray machine 200 begins fluoroscopy; pressing the second button activates the second relay, closes the two-way switch of the second relay, and the mobile X-ray machine 200 begins image acquisition.

[0054] The remote control device 100 also includes a power supply, which is electrically connected to the wireless remote control assembly 10 and is used to supply power to the wireless remote control assembly 10.

[0055] The frequency of the U-band radio frequency signal is adjustable. By using an adjustable frequency, multiple devices and multiple remote control units can be used simultaneously without interference. Frequency hopping (FHSS) and frequency modulation (FM / FSK) technologies can effectively improve anti-interference capability, transmission reliability, and security. The frequency hopping scheme is designed as follows: Frequency hopping sequence: A set of preset frequencies (e.g., 433.05MHz, 433.10MHz, 433.15MHz, etc.) are switched according to a pseudo-random sequence (e.g., a key-based algorithm); the frequency hopping interval (e.g., 10ms~100ms) must match the remote control command transmission time; transmit and receive synchronization:

[0056] For the transmitter, a synchronization header (containing the initial key or timestamp of the frequency hopping sequence) is sent before each command is transmitted. For the receiver, the subsequent frequency hopping sequence is predicted based on the synchronization header, and the receiving frequency is dynamically adjusted. In terms of hardware, the transmitter uses a frequency hopping-enabled RF chip (such as Si4463, CC1101); an integrated frequency synthesizer (PLL) is used to achieve fast frequency switching; the receiver uses a wideband receiver (covering 433MHz±5MHz) in conjunction with frequency hopping control logic, and the frequency hopping sequence is parsed in real time by an MCU.

[0057] Replacing traditional ASK modulation with frequency modulation (FM) or frequency shift keying (FSK) can improve signal noise immunity. FSK modulation maps digital signals "0" and "1" to two different frequencies (e.g., 433.92MHz ± 50kHz); the frequency deviation (Δf) must comply with regulations for the 433MHz band; modulation parameters: select an appropriate frequency deviation (e.g., ±25kHz) to balance interference immunity and bandwidth usage; the data rate (e.g., 1kbps~10kbps) should be matched to the frequency deviation to avoid inter-symbol interference.

[0058] From a hardware perspective, the transmitter uses an FSK-enabled RF chip (such as NRF905 or SX1276) and controls the carrier frequency via a DAC or digital modulation interface. The receiver uses coherent demodulation or a frequency discriminator to extract the baseband signal and integrates automatic frequency control (AFC) to compensate for frequency drift.

[0059] Combining frequency hopping and frequency modulation techniques leverages the advantages of both to achieve higher reliability. Layered modulation: Each frequency point uses FSK modulation on top of frequency hopping. For example, a frequency hopping sequence contains 10 frequency points, each transmitting data in FSK. Adaptive switching: Monitoring channel quality dynamically selects between frequency hopping and frequency modulation modes: Frequency hopping + FSK is enabled in high-interference environments. In low-interference environments, it degrades to fixed frequency + FSK to reduce power consumption. Hardware selection: Choose an RF chip that supports both frequency hopping and FSK (e.g., Si4432). Define a frequency hopping synchronization mechanism (e.g., time-based or GPS-based synchronization). Add a modulation method identifier (frequency hopping / fixed frequency) to the data packet header. Disable frequency hopping in low-power mode, using only FSK. Trigger frequency hopping mode via a wake-up signal (e.g., low-frequency 125kHz wake-up).

[0060] The remote control device 100 also includes a housing, inside which the first controller 101, the transmitting module 102, and the first antenna 103 are disposed. The housing is used to protect the internal components and improve the service life of the remote control device 100.

[0061] This embodiment also discloses a mobile X-ray machine 200 system, including the aforementioned remote control device 100 for the mobile X-ray machine 200.

[0062] The mobile X-ray machine 200 system includes a mobile X-ray machine 200. The second controller 201 is electrically connected to the device interface of the mobile X-ray machine 200 and controls the mobile X-ray machine 200 to execute commands according to the control signal. Wireless control based on UHF radio frequency signals has a long transmission distance, strong diffraction capability, and weaker attenuation than Bluetooth and infrared. The remote control device 100 using UHF radio frequency signals can well meet the needs of compartment operation.
